摘要

为提高载人潜水器多开孔耐压柱壳结构的性能，利用Abaqus软件对初始方案进行分析。设计多开孔耐压柱壳参数化分析流程，采用最优拉丁超立方方法在设计空间进行样本的选择及分析，对设计变量对于响应的影响程度进行分析，建立具有较高拟合精度的四阶响应面多开孔耐压柱壳近似模型。以耐压柱壳质量和极限强度为目标函数，基于构建的近似模型建立多开孔耐压柱壳多目标优化模型，利用第二代非支配排序遗传算法进行求解。结果表明, Pareto解集中的解在部分指标上得到优化，但优化的方面和程度不尽相同，为多开孔耐压柱壳优化方案的选择提供了依据。

Abstract

In order to improve the structural performance of the multiple openings pressure cylinder shell of manned submersible, the initial scheme was analyzed by ABAQUS software, the parametric analysis process of multi openings pressure cylinder shell was designed, the optimal Latin hypercube method was used to select and analyze the samples in the design space, the influence of the design variables on the response was analyzed, and the approximate model of multiple openings pressure cylinder shell with higher fitting accuracy was established. Taking the mass and ultimate strength of pressure cylinder shell as the objective function, the multi-objective optimization model of multiple opening pressure cylinder shell was established based on the constructed approximate model, and to solve by using the second generation of non dominated sorting genetic algorithm. The results show that the solution in Pareto solution set is optimized on some indexes, but the optimization aspects and degrees are different, which provide basis for selecting the optimization scheme of multiple opening pressure cylindrical shell.

Key words： cylindrical pressure shell; multiple openings; approximate model; multi-objective optimization
